Problems solved by technology

However, LVDT is mainly used in industrial metrology in the field of machinery manufacturing. Although the measurement resolution and accuracy can meet the requirements, due to the rigidity of the contact point, it will affect the growth of crops, and it cannot well meet the actual requirements for crop measurement.
Some scholars also use sensors or micrometers to measure the fruits or leaves of crops, but these methods all require contact operations with the fruits or leaves of crops, and measure the slight changes in pla

Embodiment Construction

[0062] The system of the present invention first obtains continuous images of crop growth conditions by an industrial camera or a digital camera, and then performs steps such as image preprocessing, image binarization, image segmentation, region extraction and calculation by a computer to obtain the stem diameter and tender buds of the crops. Crop growth status parameters such as shape and leaf color, while obtaining temperature and humidity sensors, soil water potential sensors and other sensor information, combined with crop growth data models, comprehensively make water shortage judgments, and use single-chip microcomputers to control solenoid valves for water release irrigation.

[0063] When using image acquisition equipment to collect crop images of crops, in order to solve the problem of image normalization during measurement, coordinate paper is placed at the back of the measured crops, and equidistant black dots are marked on the coordinate paper to facilitate later ima...

Abstract

The invention relates to the fields of image processing technology, the sensor technology and the water-saving irrigation, disclosing a crop irrigation system combined with computer vision and multi-sensor, wherein the technology adopted by the invention is non-destructive crop water-lacking detection combined with computer vision and multi-sensor; the system comprises the steps of obtaining and dividing a crop image, and extracting characteristic parameters; computing the characteristic parameters according to a growth data model; and then combining sensor data of a soil water potential sensor, a temperature and humidity sensor and the like, finally, finishing judgment by a genetic neural network, and controlling a single chip to drive an electromagnetic valve according to a judgment result to finish crop irrigation. The system can obtain water requirement information of crops immediately, achieve accurate irrigation immediately, and improve the utilization rate of water resource. The system has good practicability and can be applied to crop plantation areas such as a greenhouse, a farmland, a nursery garden and the like.

Description

technical field [0001] The invention relates to the field of computer vision and processing technology and sensor technology, in particular to a water-saving irrigation method based on computer vision and sensors to detect crop shape, color change and environmental parameter change and make judgment and irrigation. Background technique [0002] With the development of science and technology, agricultural production is also rapidly changing the traditional farming mode, modern science and industrial technology has gradually penetrated into agricultural production, agricultural technology is gradually developing in the direction of scientific and informationalization, modern facility agriculture Emerged as the times require, and become one of the most dynamic industries in the world today. [0003] In foreign countries, the development of water-saving irrigation control system started earlier, with a high degree of automation, and a relatively complete irrigation control syste...
